The pup isn't working out!

I had to go on a trip 2 days after we got Teddi and my wife called me on the trip to explain that she didn't think Teddi was going to work out. He wasn't sleeping at night and soon her parents would be arriving to stay with us and she didn't want Teddi to keep them awake. By this time I was being stubborn, we were over $600 in cost into this dog and we sure weren't going to give up this quickly.
